A Denver marijuana-infused manufacturing facility, RevTec, is voluntarily recalling marijuana products due to the presence of potentially unsafe pesticide residues found in product samples. The recall affects 5,825 individual units of five different products.

Recalled products include marijuana concentrates that are typically used for smoking or vaporizing. The products were derived from contaminated plant material purchased from River Rock, a cultivation facility in Denver. Samples of these marijuana concentrates tested positive for two pesticides that the Colorado Department of Agriculture has determined cannot be used legally on marijuana in Colorado: Imidacloprid and Myclobutanil.

There have been no reports of illness. The possible health impact of consuming marijuana products with unapproved pesticide residues is unknown. Short- and long-term health impacts may exist depending on the specific product, duration, frequency, level of exposure, and route of ingestion. Consumers with concerns about their personal health should contact their physician with related questions.

The Denver Department of Environmental Health (DEH) is investigating this issue and overseeing the recall process to remove potentially contaminated product from commerce. DEH conducts inspections of marijuana-infused product manufacturers and retail locations in Denver and investigates related complaints.

Consumers with questions or concerns about recalled product or pesticide residues in marijuana products are encouraged to contact the product retailer and/or the DEH Public Health Inspections division at phicomments@denvergov.org or 720-913-1311.
